Inventor: BALES THOMAS O
IPC: D07B1/00
Filed: 2000-10-12
Abstract: A multifilar flexible rotary shaft (100) includes a plurality of individual filaments (102, 104, 106, 108, 110, 112, 114) which are not wound around each other or around a central core, a loose ensemble of filaments. The input ends (1) of each filament are coupled to each other and the output ends (O) of each filament are coupled to each other. Preferably all of the filaments are identical. A loose ensemble of N filaments can transmit N times the torque of a single filament, and will have N times the torsional stiffness of a single filament, while retaining the minimum radius of operation of a single filament. Since a loose ensemble of filaments does not have any appreciable contact forces among the filaments (because they are not forcibly twisted together), there is no appreciable internal friction or hysteresis. In order to appreciably eliminate all the hysteresis in such an ensemble of filaments, the filaments should be no more than loosely twisted together, if at all. The only reason for loosely twisting the wires together is to allow the ensemble to be easily handled and to insure that the individual wire filaments follow the same general curved path from one end to the other. Several practical applications of the invention are also disclosed.

Title: Polyphase encapsulated outdoor high-voltage switching device
Inventor: SUHR MICHAEL
IPC: H02B13/02
Filed: 2000-01-25
Abstract: In a polyphase encapsulated outdoor high-voltage switching device, the circuit breakers are arranged horizontally in a tubular switch enclosure which is provided at the ends with connecting flanges for connection of further encapsulation modules. Such encapsulation modules are, in particular, direction-changing modules, by means of which the directions of the electrical connections of the interrupter units of the circuit breaker are changed into branching cable connections. These encapsulation modules may, in particular, be angled splitting modules with associated outdoor bushings, and disconnector-grounding device modules. When using direction-changing modules which change the direction of the current path horizontally through 90°, H-circuits can be produced such that all the modules are arranged in a horizontal plane. The switching device thus has little physical height.

Title: Air spring vehicle suspension with roll control and negligible creep
Inventor: RICHARDSON GREGORY A
IPC: B60G5/00
Filed: 2002-03-18
Abstract: A trailer suspension comprises a pair of beams mounting a pair of axles and fluidly interconnected air springs. During normal forward travel, when one axle traverses a bump, the air springs have a low spring rate. During cornering, the spring rate is much higher to provide roll resistance. Bumpers limit the roll on an outboard side of the trailer. A flexible connector between the beam and frame further limits roll on an inboard side of the trailer. The beam is pivotally mounted to a vehicle frame rail through a relatively long radius rod thereby reducing creep to a negligible amount.

Abstract: A method for producing fumed silica and a fluorine-containing product from a source of silica in solid form and a solid material containing fluorine, the solid material selected from the group consisting of sodium aluminum tetrafluoride, cryolite, aluminum fluosilicate, ammonium bifluoride, sodium aluminum silicofluoride, and sodium flurosiliate. The method comprises the steps of digesting the silica in solid form and the solid material selected from the group consisting of sodium aluminum tetrafloride, cryolite, aluminum fluosilicate, ammonium bifluoride, sodium aluminum silicofluoride, and sodium flurosiliate in a sulfuric acid digester. The digesting step produces a first gas component comprised of silicon tetrafluoride, hydrogen fluoride and water vapor. The first gas component is removed from the digester. The gas component recovered from the digester is heated to a temperature sufficiently high to convert the silicon tetrafluoride to fumed silica in the presence of the hydrogen fluoride and the fumed silica is separated from the hydrogen fluoride.

Title: Polyols for breaking borate crosslinked fracturing fluid
Inventor: CREWS JAMES B
IPC: C09K8/502
Filed: 2002-06-28
Abstract: It has been discovered that borate crosslinked fracturing fluid breaker mechanisms are improved by the inclusion of a polyol together with an enzyme. In fact, synergistic results may be achieved when both are used together as contrasted to the cases where each are used separately.     Removing the borate ion from the crosslinked polymer reduces the pH of the fluid and in turn increases the activity of the enzyme. That is, once the pH  is lowered, viscosity reduction (breaking) occurs by uncrosslinking of the polymer within the fracturing fluid, and by initiating or increasing activity of an enzyme breaker, if present. In one embodiment, the polyol has at least two cis-hydroxyl groups. In another embodiment, the polyols are monosaccharides such as glycerols and sugar alcohols, and may include mannitol, sorbitol, glucose, fructose, galactose, mannose, allose, etc. and mixtures thereof. Oligosaccharides and derivatives of monosaccharides and oligosaccharides are also useful.

Patent CA-2401901-A1 (CA)
Inventor: BARRY CHARLES F
IPC: H04L12/437
Filed: 2001-03-02
Abstract: The disclosed network includes two rings, wherein a first ring transmits data in a clockwise direction, and the other ring transmits data in a counterclockwise direction. The traffic is removed from the ring by the destination node. During normal operations (i.e., all spans operational), data between nodes flows on the ring that would provide the minimum number of hops to the destination node. Thus, both rings are fully utilized during normal operations. The nodes periodically test the bit error rate of the links (or the error rate is constantly calculated) to detect a fault in one of the links. The detection of such a fault sends a broadcast signal to all nodes to reconfigure a routing table within the node so as to identify the optimum routing of source traffic to the destination node after the fault. Since the available links will now see more data traffic due to the failed link, traffic designated as "unprotected" traffic is given lower priority and may be dropped or delayed in favor of the "protected" traffic. Specific techniques are described for identifying a failed link, communicating the failed link to the other nodes, differentiating between protected and unprotected classes of traffic, and updating the routing tables.
